“…Mixer based circuits, either in microstrip [5,6] or monolithic technology [7][8][9], tipically use diodes [10][11][12] or transistors [13][14][15] as active components, in order to generate the nonlinear behaviour. Creating wideband mixers in microstrip technology can be a real challenge for many designers.…”

Abstract-In this work, a millimeter wave microstrip frequency-mixer design based on graphene is presented. The desired frequency mixing behavior is obtained using a nonlinear component consisting in a microstrip line gap covered by a graphene layer. The circuit includes microstrip filters that have been designed to obtain a high isolation between the input and output ports. The nonlinear behavior of the frequency mixer has been experimentally evaluated in the 38.6-40 GHz input signal frequency range, for different values of the input power and local oscillator power.

“…Image rejection mixer (IRM) is one of the most common methods to avoid noise interference from image frequencies in receiver systems. The anti-parallel diode pair (APDP) topology has been commonly used for diode mixers, particularly subharmonically pumped mixer [4]. However, compared with other types of diode mixers, the APDP topology of the subharmonically pumped mixer occupies a large chip dimension.…”

Abstract-A broadband monolithic image rejection subharmonic mixer using a standard 0.18 µm CMOS technology is proposed. This circuit is composed of a band-pass filter with an intermediate frequency (IF) extraction function that can simplify the block diagram of the image rejection mixer. The entire passive circuit is constructed using a broadside coupling structure to achieve a high level of integration. Based on measured results, the proposed mixer exhibits conversion loss of 15.5-18.5 dB at a local oscillator (LO) power of 13 dBm, whereas the 3 dB bandwidth ranges from 20 to 31 GHz (43.1%) with a miniature chip dimension of 0.77 × 0.81 mm 2 . The LO-to-radio frequency (RF), 2LO-to-RF, and RF-to-IF isolation levels are higher than 22.5, 42.9, and 34.5 dB, respectively. The best image rejection ratio of 29 dBc with 20 • phase compensation at 24.5 GHz can be achieved.

“…There are several general types for millimeter-wave mixers. The harmonic mixers [2][3][4][5][6] can mix the input signal and the even harmonics of LO without a multiplier, but it is difficult for them to achieve low conversion loss. Resistive mixers [7,8] have the advantages of low distortion and lower conversion loss.…”

A 26∼40 GHz millimeter-wave monolithic passive IQ mixer was designed by using Win's 0.15-µm GaAs pHEMT process. It utilizes a ring diode structure, and the performance can be improved effectively by a modified Marchand balun and U-type coupled lines. Through on-wafer measurement, the mixer shows a conversion loss of 6.6∼9 dB over a bandwidth of 26∼40 GHz, an IF bandwidth from DC to 6 GHz, an image rejection ratio of 21∼30 dB, an LO-RF isolation of above 24 dB, an LO-IF isolation of above 35 dB, and an RF-IF isolation of above 25 dB.
